Discussion
A series of weather fronts moving east across the north slope
over the next few days will be our main forecast challenge today.

These fronts will bring precipitation along with gusty winds to
the north slope. South of the brooks range, each of these systems
will scattered showers and gusty winds (especially in the northern
part of the interior).

The models are in relatively good agreement with the main
synoptic scale features out through Saturday. Thereafter they
begin to diverge on the details of the synoptic scale pattern;
however, they generally show a ridge building in over the
southern and eventually eastern interior late this weekend into
early next week.

Interior: scattered showers and isolated thunderstorms are
expected this evening, primarily southeast of a line from
chalkytsik to mcgrath. A surface low moving across the brooks
range will bring some gusty west to southwesterly winds to areas
north of the yukon river this evening. Temperatures for Friday
will be a few degrees cooler than today for most locations across
the interior, with the warmest conditions expected over the yukon
flats. The airmass over most of the interior will be more stable
on Friday, with isolated thunderstorms confined to areas right
along the canadian border. Elsewhere, there could be a few showers
around; however, it will likely be very spotty. The cooling trend
will continue on Saturday. Any thunderstorms on Saturday will be
confined to areas to the southeast of tok. A weather front
associated with a low moving across the arctic coast will bring
increased chances for showers as it moves from west to east
Saturday and Saturday night. This front will also cause
southwesterly winds to increase across most of the interior;
however, the strongest of the winds will be along and north of the
yukon river. A ridge aloft will build back over the interior
Sunday into early next week. A warming trend in temperatures is
expected as the ridge builds back in; however, the models differ
in the exact details of how this will play out at the moment.

North slope and brooks range: a front will bring rainfall to most
areas north of the brooks range as is moves from west to east
tonight. Winds will turn westerly and increase behind the front;
however, the strongest winds with this system are expected to
remain north of the coast, as the low associated with the front
will remain well north of the coast. A second low will move
northeast across the arctic coast on Saturday. This low and the
associated front will bring stronger winds than the first low
along with more precipitation. The models still have differences
in the placement and strength of this system.

West coast: a weather front will bring more organized rainfall to
areas north of the seward peninsula tonight. A second front will
bring (heavier) rainfall on Saturday to the northwest arctic.

This second front will bring strong southwesterly winds to the
northwest arctic coast early Saturday morning.

Coastal hazard potential days 3 and 4... None.

Fire weather
Isolated thunderstorms are expected in the eastern interior and
along the alaska range this evening.

A cold front will pass through the interior tonight. This front
will bring cooler temperatures for Friday for most of the interior
with an increase in rh values. The cooling trend will continue
through for Saturday. The airmass behind the front will be more
stable, limiting chances for thunderstorm development. On Friday
isolated thunderstorms confined to areas right along the canadian
border, while on Saturday any thunderstorms will be confined to
areas to the southeast of tok.

Hydrology
0.25 to 1.0 inches of rainfall is across much of the north slope
and the brooks range as a series of systems move through the
area. This will cause some minor rises in rivers that drain the
brooks range.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
